Will some good natured UHH give me some first-hand pros and cons of the Canon7DII? I know it's a crop...I would like to know if it has pleased you owners, or disappointed you and why. I'll be using it for mostly wildlife, birding, overcast/low light conditions. Have you had any problems with it and a particular lens?
I used a pair of 7DII beginning last year and find them very reliable and good performing cameras. It's a nearly ideal camera for wildlife, birding and the sports/action shooting I do a lot (a bit over 60,000 images with the two 7DII last year). The only Canon "better" for action/sports would be the 1DX-series models... but those are full frame so also would need to be used with much more expensive telephotos that are a lot bigger, heavier and make me less mobile. For this reason, I prefer crop sensor cameras for a lot of things.
I've used my 7DII's with around fifteen or twenty different lenses and haven't seen any problems at all (at least none related to the cameras). I've used EF-S 10-22mm, EF 24-70mm, EF 70-200/4 and EF 70-200/2.8, EF 300/4 lenses a lot with it. Also got EF 100-400 Mark II midway through last year and use it quite often on 7DII. And I've used Tamron SP 60mm macro sometimes as well. Other lenses have all been fine, too... just haven't had need to use them a lot... yet.
Image quality is excellent. For low light it rivals the full frame 5D Mark II I've been using for that purpose for some years (a 5DIV upgrade is probably next on my to-do list)... and at high ISO the 7DII are an improvement on the pair of original 7D I shot with for about five years (around 250,000 images). I have used all three models as high as ISO 6400. At that high ISO the 7DII's images aren't "noise free" by any means, but they are quite usable for most purposes. And they require less post-processing "help" than original 7D's high ISO images did. 1DX-series 6D, 5DIII, 5DIV are all likely a little better high ISO/low light cameras.
80D is a viable alternative. It's not got quite as fast frame rate, isn't rated as high for durability or as well sealed for weather resistance, and doesn't have quite as customizable/high performance auto focus as 7DII... But 80D is no slouch, by any means. It has a one generation newer, 20% higher resolution sensor with slightly greater dynamic range. And it's unique AF system has a whole lot more "f8 capable" points than 7DII (27 versus 1), so if using teleconverters a lot, might be a good choice. The articulated LCD of 80D can be handy for some things, too... 7DII's screen is fixed (which might be better for weather resistance and durability). If using Live View a lot... both cameras have Canon's much improved Dual Pixel autofocus that makes it far more usable... but that might be even a little more useful on a screen that can be tilted for high and low angle shots. The 80D's is a Touch Screen. The 7DII's isn't.
Depending upon the cameras you've used in the past, the 7DII's 65-point AF system might be easy or difficult to learn to use well. It's basically an upgraded and expanded version of the original 7D's 19-point and is highly customizable and "tweakable". That's great when it's used right... But it also can get you into a world of trouble if used wrong!
I usually use 7DII AF pretty simply... Single Point/Manual selected. That requires me to work harder to keep the AF point right where I want camera and lens to focus, but still is the best way to insure a high percentage of accurately focused shots (I probably see fewer than 2 or 3% missed focus... and I bet at least half of those are my errors, not the cameras'.) In certain situations I sometimes use Zone Focus (Large and Small) and Expansion Points (4-point and 8-point). And I find Spot Focus useful at times (that's a higher precision form of Single Point/Manual, though slightly slower). I can't recall ever using All Points/Auto with 7DII (or any other Canon model, for that matter).
80D doesn't have all these AF patterns... It offers All Points, Single Point (like all Canon), Large Zone and Zone Focus. 80D doesn't have Expansion Points or Spot Focus modes.
I mostly use fast-focusing USM lenses and with them have had no problem with 7DII's AF tracking moving subjects. 7DII and the original 7D are both similar to 1D-series cameras, with a separate, discrete chip running the AF (while dual processors handle the images). Most other Canon models that I'm aware of use a single processor to handle both AF and images (I think 5DS models use dual processors, but still don't handle AF separately).
The 7DII's metering system is also improved over the original 7D's. I still use some ETTR with it, but find I don't need to set quite as much.
As to high ISO performance, here's an ISO 16000 (yes, that's sixteen
thousand) test shot with 7DII...
Above was shot about 8 feet from a small window and 10 or 12 feet from a single 60 watt light bulb. It was shot RAW with care to avoid underexposure, converted in Lightroom with default settings except for a slight boost in contrast (noise reduction at default settings). Sure, there's some noise in the image. But IMO it's pretty well controlled and image is fully usable at Internet sizes and resolutions. Probably printable up to about 8x10/8x12, too.
My only minor complaints about the 7DII are that the AF-On, * buttons are a little small and close together, harder to differentiate by touch, compared to earlier models I've used a lot. Or maybe it's that my thumb is too big. It matters to me because I use BBF virtually all the time. Took some getting used to.... I've had some missed focus and unintentional AE locks. Other controls are excellent... expecially the more direct access to changing the AF pattern and the secondary joystick on the vertical/battery grip.
The "abridged" printed user manual is another minor complaint of mine... Canon includes a 150 page manual with the camera. But the "real" manual is around 500 pages... Plus another 50 page manual specifically for the AF system. When I bought my cameras there weren't many guide books, either. There are more now. (Any time I get a new model of camera, I always get a guide book for it, to help shorten the learning curve.)
